self bleeding radiator valves

ilya980

Hi,

I want to install self-bleeding radiator valves on all my radiator. I have 2 installed already, but I have other radiators with regular caps and they are sometimes difficult to bleed. I was looking at Watts or Taco self bleeding valves (1/8''). The problem is that all valves come with the male threaded connector. All my radiators (except the two with these valves already) have 1/8'' thread. The thread is sticking out of the radiator and a part of the radiator (like a bike nipple) How do I install these valves? Do I need female-female 1/8'' coupler???

Thanks.
